VIOS 为Power lpar扩容 （转）

????此文上半部分创建vg转载某高人，后半部分将新分配磁盘空间挂载到rootvg为原创。?
一、为lpar新增磁盘空间 点击原文地址?
??? 言：一个P550小型机，两个300G硬盘，hdisk0和hdisk1，利用PowerVM技术建立三台虚拟机，AIX1独占1个300G硬盘hdisk1，hdisk0使用vios建立成一个rootvg，AIX2和Linux for power分别使用rootvg两个100G的LV，日常使用中AIX2空间不足，需要给AIX2扩容。下面将使用VIOS、AIX2作为前缀说明执行的环境。
?
1. 查看VIOS环境和AIX当前环境

可见AIX2只挂载了一个分区。下面利用vios创建一个给AIX2使用的vg
?
2. 新建磁盘空间并分配给AIX2
???? VIOS：#mklv -y aix2datavg -t jfs2 rootvg 50G??
??? //命令解释：在rootvg创建一个50G名为aix2datavg的jfs2格式的lv
??? aix2datavg
??? lv创建完毕，下面将lv映射给AIX2?
??? VIOS：$mkvdev -vdev aix2datavg -vadapter vhost1????
??? //命令解释：创建一个虚拟设备，并映射给vhost1(即AIX2,由lsmap命令知道)，可以加-dev参数为新虚拟设备命名
??? vtscsi0 Available
??? 由于没指定虚拟设备名称，此处系统默认分配了一个vtscsi0。执行lsmap查看是否已经映射成功。
??? VIOS：$lsmap -all

????
??? 可见vhost1已经增加了vtscsi0，然后利用HMC管理平台重启AIX2
??? AIX2：# lspv
??? hdisk0????????? 00c28ad458c8499d??????????????????? rootvg????????? active
??? hdisk1????????? none??????????????????????????????? None??????????
??? AIX2已经成功添加了一个pv hdisk1
二、将分配磁盘空间挂载到已有的rootvg上
1. 给hdisk1创建vg
??? AIX2：# mkvg hdisk1
??? 0516-1254 mkvg: Changing the PVID in the ODM.
??? vg00
??? AIX2：# lspv
??? hdisk0????????? 00c28ad458c8499d??????????????????? rootvg????????? active
??? hdisk1????????? 00c28ad46d8b5773??????????????????? vg00??????????? active
?
2. 将hdisk1加载到rootvg上
??? 如果已经进行了1操作，需要将vg00从hdisk1上干掉，命令:
??? AIX2：# reducevg vg00 hdisk1
??? 然后将hdisk1挂载到rootvg上，命令:
??? AIX2：# smit vg

??? 至此，本次给AIX2扩容已经完成
